Product Details

DFC Geospec Rotors with 5000 Advanced Brake Pads includes Hardware is engineered for rear brake service on 2018-2020 Chevrolet Express 2500, 2018-2020 Chevrolet Express 3500 with 3.42" gear ratio, 2018-2020 GMC Savana 2500, and 2018-2020 GMC Savana 3500 with 3.42" gear ratio. The DFC 5000 pad formulation is developed around OE-style friction requirements, while the GeoSpec rotor casting uses G3000/G11H18 cast iron and tight machining tolerances for durability, reliability, and stable braking feel. Part number 4512-48238 is a practical choice for rear brake refreshes where rotor finish, pad consistency, and hardware condition all matter.

Common Repair Uses

• Rear brake noise from worn pads or fatigued hardware
• Rust buildup on rotor surfaces
• Uneven braking feel or reduced stopping response
• Premature or uneven pad wear
• Brake service on high-use Chevrolet Express and GMC Savana vans

Installation Notes

Compatible With rear brake service on the listed vans only. Inspect calipers, slides, and mounting points before installation, and replace any worn components that could affect pad movement or rotor alignment. The dry rotor coating is removed naturally by the friction material during normal braking. Part number 4512-48238 should be matched to the vehicle’s rear application and gear-ratio note where listed.

Quality Assurance

Each rotor is machined to OE-level specifications, inspected for critical dimensions, and vented rotors are balance-checked and corrected when needed. DFC also performs 100% inspection on finished rotors for material and workmanship consistency. Rotors include a 12-month warranty against defects in material and workmanship. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
